Abstract:
A silver-based alloy composition which is soft and workable in an annealed condition, is hardenable through heat treatment, and is tarnish resistant. The preferred embodiment of the composition of the present invention includes a small percentage of palladium and a reduction from typical percentages of copper found in a sterling silver alloy. In one embodiment the silver-based alloy includes no copper at all.
